ISO Published ISO 8124-6:2018 On Phthalates

Time : 2019-04-02 14:29:33
ISO has published ISO 8124-6:2018 for phthalates in toys and children’s products. The new standard replaced the first edition upon publication.
In November 2018, ISO published ISO 8124-6:2018 . This second edition contains, inter alia, a number of important technical revisions to its predecessor. These include the following:
· Extending the suitability of the method from six phthalates (BBP, DBP, DEHP, DIDP, DINP and DNOP) to seven phthalates (BBP, DBP, DEHP, DIBP, DIDP, DINP and DNOP)
· Inclusion of ‘liquids’ to the specific list of materials that are applicable to toys and children’s products
· The use of ‘ultrasonic bath’, described as Method C, for extraction as an additional suitable method to ‘Soxhlet extraction’ and ‘Solvent extraction’
The ISO 8124-6:2018 standard replaced the first edition upon its publication.
A comparison of major highlights between ISO 8124-6:2018 and its predecessor is summarized in Table 1.
